To all whom it may concern: the frame 12 the shaft 1 passes through a Be it known that I, WVILLARD G. Srnrnns. bracket 18 spring from the head 2 and upon a citizen of the United States, residing at this bracket and also pierced by the shaft 4 is Newburyport, in the county of Essex and fixedly mounted a gear 19 which cooperates State of Massachusetts have invented a new with other parts to turn a reel as will hereinand useful Improvement in Twisting-Maafter he explained. chines, of which the following is a specifical/Vithin the frame l2 is rotatably and retion, reference being had therein to the acmovably mounted a reel 20 upon which is companying drawings, wound the finished string 01' cord 9 as it 1.5 This invention relates to twisting matwisted by the rotation of the shaft 4: and chines for making string or cordage or for frame 12. The reel 20 when full is removed co ing th m with a m t llic nv lo from the machine and an empty reel mount- The objects of the invention are, first, to ed therein and in order that this change may afford facilities for operating the machine be accomplished as expeditiously as possible at a very high rate of speed and thereby the following means are provided. The make it highly productive; second, to proreel 20 turns on two spindles 21 and 22 set vide for the reeling of the product i as fast in opposite sides of the frame 12, the spindle as it is finished and independently of the 92 being movable longitudinally within a speed of the machine and, third, to permit Sleeve 23 secured in the frame 12. The spinthe reel when full to be quickly and easily dle 22 has near its lower end an enlarged removed and an empty reel installed; portion 24 which serves a double purpose.

The reel may be released by unscrewportion 2 on which is mounted, in suitable ing the knurled nut 26 instead of using a bearings, a shaft 4, held by a top-plate 5 setool in the aperture but the former method cured to the head-portion 2 by bolts 6. An is more expeditious. The outer face of the oil-cup 7 in the top-plate 5 provides for the enlarged portion 2 1 bears against one side lubricating of the shaft 1 which is bored of the reel 20 to prevent the spindle enterlongitudinally, the boring 8 being of a size ing the hub of the reel too far and also to sufficient to receive the cord or string 9 force the reel against a friction spring made or covered by the machine. At one secured to a beveled gear 29 which turns on end the shaft 1 is provided with a drivingthe fixed spindle 21.' The friction spring pulley 10, driven by a belt 11, and upon the 28 has a plurality of arms, each carrying a other end is mounted a frame 12 which is leather shoe 30 which contacts the side of the secured on the shaft between a collar 13 and reel 20 and tends to carry the reel around a nut 14 and rotates with the shaft. The when the gear 29, to which the spring is at other end of the frame 12 is provided with tached, rotates. Gear 29 is held in place on a spindle 15 which is journaled in suitable the spindle 21 by set-nuts 31, and is turned bearings 16 on hangers 17 attached to the by a beveled-pinion 32 mounted on one end. floor.

The other end of the shaft 33 passes it may be rotated at practically an unlimited throughthe end of the frame 12 nearest the rate of speed without vibration or danger head 2 and carries a gear 35 which meshes t0 the machine. Between the head 2 and with, the fixed gear 19. In order to counterbalance the weight of these gears and shaft a-fcounter eight 36 is secured on the other s'id'eof the frame 12. j

The machine, which is not automatic in that it requires the constant attendance of permitting 'the materials to be drawn through his hands as fast as required. When the machine is operated, the shaft 4 and frame 12 are rotatedwat a hi hrate of speed Whiclrof course: twists together the materials lbetween' the reel and the hands of the operator. As theytwisting process continuest-he operator permits the finished product tozbedrawn into the machine bythe-reel 20 and Wound :up thereom As the-frame 1.2 rotates; the gear 35, meshing With the fixed gear-'19,:travels around the latter and is thereby rotated turning the gear 29 through the medium ofithe rod 33 and beveled-pinion 323 The leather-shoes 8O on 'the friction spring'-, 28 bear against the reel 20 and tend to-tnrn it With-the gear 29. The twisting of the reel 20?, is, hoi'vever, under the direct c0ntrol:of-the ioperator and 'unlesshe releases the materi'alor string'fi) the reclicannot be turned and the shoes 30 slide on the side of the reel. The moment-the iop'erator releases the string 9 the'shoes on the 'frict'ion spring catchvth'e side of the reel and turn it until the-slack in the string 9 is Wound onthe reel. wW'hen the reel 20 is filled; the machine is= stoppedmomentarily, the 'string9 is cut near-the reel, the spindle 22 is raised against thepressure of thespring 25 byaneans of a toolrinserted in the aperture 27"or-is re leased'byunscrewing the knurled nut 26 and the reelis removed 'from"the"1nachine; An emptyrreel is atonce installed by placing it on-spindle 21 permitting spindle-22 tobe forced into the other end of thehub of the reel%hy"the spring" 25 and thensecuring the string :'9I'to' the reel. :It is obvious that the operation 'o fichanging the-reel-on the machine may beaccomplished Withgreat facility" and'ina moment, thus'hardly interferingavith the continuous operation of the machine. r

PHIt is to be observed, and this is an iinporta-nt fe'atur e :of the machine,- that the frame I which carries-the reeling mechanism is supported at both ends and is evenly balanced. 1

This construction presents N several advantages." In the first place it greatly increases the production ofthe machinefsi ite the pro duction depends entirely upon thjs eed of the machine and this construction permits running the machine at a very high rate of speed Without danger. Secondly, there is little or" no'vibration and the Wearandtear on 'the niachine' dueto that cause is practically eradicated. Thirdly, it permits the various parts to'hemademuch lighter and yet-justas serviceable]qtal r m? a; I Another importantfeature resides; inlwthe means employed for reeling 'upthe finished product as fas'tas it is prodnced and under theFcOniplete control of the operator. Great difficulty has heretoforfe been e'xperienced in the use of gearsfor this purposeyowing-to the fact that as the reelg fillsyup eachgrevohn tion ofit ivinds up a; longerf portion:bfthe product. By the use of theifriction-spring, however,=the;speed ofwthe'wreel can be controlled exactly by the operator.
